Wouldn't hurt to call any Toyota dealer. They love recalls and make mega-bucks fixing them.
I remember my '90 Jeep Wrangler had a parking brake recall once. It was used to haul my boat into the water and back, and I would never trust it on the road. Jeep said to bring it in for a free fix, and when I just asked for the parts, they declined saying it was a safety issue and they could not guarantee my work was sufficient to stop a lawsuit if I screwed up.
